There are three client options for Mac OS X.:
The OpenVPN command line client. Most users prefer a graphical client, so thisoption will not be covered.
Tunnelblick, a free option available for download at the Tunnelblick Website.
The commercial Viscosity client. At the time of this writing, it costs $14USD for a single seat. If OpenVPN is used frequently, Viscosity is a muchnicer client and well worth the cost.
Both Tunnelblick and Viscosity are easily installed, with no configurationoptions during installation.

Viscosity Details¶
Clicking the up/down arrow button in the middle of the details screen displaysadditional network traffic statistics. This shows the traffic sent within thetunnel (TUN/TAP In and Out), as well as the total TCP or UDP traffic sentincluding the overhead of the tunnel and encryption. For connections usingprimarily small packets the overhead is considerable with all VPN solutions. Thestats shown in Figure Viscosity Details: Traffic Statistics are from only afew pings traversing the connection. The traffic sent in bringing up theconnection is also counted here, so the initial overhead is higher than what itwill be after being connected for some time. Also, the typical VPN traffic willhave larger packet sizes than 64 byte pings, making the total overhead anddifference between these two numbers considerably less.
